Technical Field

[0001] The utility model belongs to the technical field of rolling mills, and in particular relates to a mounting piece used for supporting a rolling roll in a rolling mill frame. Background Art

[0002] A rolling mill is a device that realizes the metal rolling process. It is composed of components such as rolls, bearing seats, frames, and unloading platforms. Among them, the rolls are the main components and tools for realizing continuous plastic deformation of metals. The rolls of different types of rolling mills not only have very different usage conditions, but also because of their different uses, the materials, metallurgical quality, manufacturing process, size and other factors of the production rolls are also different.

[0003] After the rolls are produced in the factory, they are transported to the destination by a transport device and installed with mounting parts. In the process of installing the rolls on the rolling mill frame by the mounting parts, due to the large weight of the rolls themselves and the need to align the ends of the rolls and install them on the bearing seats of the rolling mill frame, the entire installation process is relatively time-consuming, resulting in the time-consuming and labor-intensive installation of the rolls. In view of this, the utility model is proposed to provide a mounting part for supporting the rolls in the roll bracket of the rolling mill frame to solve the above problems. Utility Model Content

[0005] The two cams are connected to each other on both sides of the roller support frame, and the two cams are connected to each other on both sides of the roller support frame.

[0006] As a preferred embodiment of the present invention, the inner wall of the first annular groove is slidably connected to a symmetrically arranged mounting plate, the outer walls on opposite sides of the two mounting plates are fixedly connected to telescopic sleeves, and the telescopic ends of the two telescopic sleeves are respectively fixedly connected to the outer walls on one side of the two fixing parts.

[0007] As a preferred embodiment of the present invention, arcuate grooves are provided on opposite sides of the two fixing members, and the two arcuate grooves are in contact with the outer walls on both sides of the left end of the roller body respectively.

[0008] As a preferred embodiment of the present invention, a mounting hole is provided in the middle of the mounting seat, and the left end of the roller body is inserted into the inner wall of the mounting hole.

[0009] As a preferred embodiment of the present invention, the outer walls of the mounting seat are fixedly connected to the connecting seat, the inner wall of the mounting ring is provided with a second annular groove, and the connecting seat is slidably connected to the inner wall of the second annular groove.

[0010] As a preferred embodiment of the present invention, a mounting shaft end is fixedly provided on the right end of the roller body.

[0011] As a preferred embodiment of the present invention, a guide groove is provided on one side of the support frame, a guide block is slidably connected to the inner wall of the guide groove, and the guide block is fixedly connected to the outer wall of one side of the lifting frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When the two ends of the roller body are fixed on the mounting base, the cylinder is started to drive the lifting frame to move downward, and the lifting frame cooperates with the two mounting frames to change the inclination angle of the two connecting rods. When the inclination angle of the two connecting rods changes, the two mounting frames, the two mounting plates and the two telescopic sleeves are cooperated to enable the two connecting rods to drive the two fixing parts to move relative to each other until the arc grooves opened on the opposite sides of the two fixing parts respectively contact the outer walls of the left ends of the roller body, thereby realizing the limiting effect of the left end position of the roller body, thereby completing the limiting installation of the left end position of the roller body, so that under the action of the support frame and the mounting ring, the left end of the roller body can be firmly supported. When the roller body is supported, the right end of the roller body can be installed on the driving shaft of the rolling mill frame. With the roller body firmly supported, it is convenient to align the left end of the roller body with the bearing seat of the rolling mill frame, so that the entire installation process saves time and effort.
